一,产品概述(General Description)
 The CXSD6282 CXSD6282A is a voltage mode, synchronous PWM controller which
drives dual N-channel MOSFETs. The device integrates all of the control, monitoring and protecting functions into a single package, provides one controlled power output with under-voltage and over-current protections.The CXSD6282 CXSD6282A provides excellent regulation for output load variation. The internal 0.6V temperature-compensated reference voltage is designed to meet the requirement of low output voltage applications. The device includes a 200kHz free-running triangle-wave oscillator that is adjustable from 50kHz to 1000kHz.
 The CXSD6282 CXSD6282A has been equipped with excellent protec-tion functions: POR, OCP, and UVP. The Power-On-Re-set (POR) circuit can monitor the VCC, EN, and OCSET voltage to make sure the supply voltage exceeds their threshold voltage while the controller is running. The Over-Current Protection (OCP) monitors the output cur-rent by using the voltage drop across the upper MOSFET’s RDS(ON). When the output current reaches the trip point, the controller will run the soft-start function until the fault events are removed. The Under-Voltage Protection (UVP)monitors the voltage at FB pin (V FB) for short-circuit protection. When the VFB is less than 50% of VREF, the controller will shutdown the IC directly.
